2 Mr. Charles Alexander Executive Director The Warner Robins Housing Authority P.O. Box 2048 Warner Robins, Georgia RE: Asbestos Survey: Project Site GA06P Dear Mr. Alexander: Holley Consultants, Inc. (HC) has completed asbestos testing services for The Warner Robins Housing Authority. The survey was conducted on and between the dates of November 1, 2005 and November 4, Field work was performed by Joey Burn and Rick Holley of Holley Consultants, Inc. Mr. Holley, an EPA Georgia accredited Asbestos Consultant/Building Inspector, conducted a survey of the units for asbestos containing materials (ACM). Work included collection of bulk building material samples of suspect ACM for laboratory analysis. Mr. Holley s asbestos inspector certification number is ASBESTOS SURVEY METHODOLOGY Multiple bulk samples of suspect ACM were obtained from various locations associated with the units. Materials sampled were grouped into homogeneous areas (materials that appeared to be of the same physical composition) for the purpose of data assessment and reporting. The bulk samples were analyzed by Schneider Laboratories, Inc. located at 2512 W. Cary Street, Richmond, Virginia. Samples were analyzed using Polarized Light Microscopy (PLM) methods with dispersion staining techniques according to U.S. EPA Method 600/R This type of analysis requires the microscopist to take a portion of the bulk sample and treat it with a special light refractive oil emulsion stain. This prepared slide is then subjected to a variety of tests while being viewed under a microscope while varying the polarization of light. This method of analysis requires the microscopist to make visual estimations and results are subject to errors inherent to visual estimations. In addition, false negative results may be caused by method limitations in separating closely bound fibers from matrix material and in detecting fibers of small length or diameter. Such fibers may be detected using Transmission Electron Microscopy (TEM). Schneider Laboratories has the capability of performing the TEM confirmation analysis if so desired. Schneider Laboratories, Inc. is an independent, fully accredited, woman-owned, small

3 Page 2 business analytical laboratory that specializes primarily in asbestos and metals analysis. Schneider Laboratories, Inc. is accredited by AIHA (#8936) for PCM (asbestos air analysis) and metals, as well as National Voluntary Laboratory Accreditation Program (NVLAP) #1150 for PLM (asbestos bulk analysis). TYPES OF ASBESTOS CONTAINING MATERIALS Friable Material: Material which can be crumbled or reduced to a powder using normal hand pressure. Non-friable material is too hard to be crumbled or reduced to a powder without the use of tools. Non-friable materials may become friable if abraded or broken. Asbestos-containing Materials (ACM): Asbestos-containing materials as defined by National Emission Standards for Hazardous Air Pollutants (NESHAP), are those materials that have an asbestos content greater than one (1) percent. Suspect Materials: There are three (3) broad categories that define suspect asbestoscontaining materials. These are: 1) Surfacing material, 2) Thermal System Insulation, and 3) Miscellaneous Material. All materials that fit the description of these materials (as described below) are suspected to contain asbestos, until sampled and analyzed. 1. Surfacing Materials: Materials applied by spray or trowel are classified as surfacing materials. Asbestos was used in a variety of surfacing materials for fireproofing, acoustic dampening, condensation control, and for decorative purposes. Surfacing materials which contain asbestos usually occur as fireproofing on steel-frame members, as textured ceiling, or as acoustical plaster ceilings. 2. Thermal System Insulation (TSI) Material: Chill water, hot water, and steam generating mechanical systems are frequently insulated with materials which contain asbestos. Many pipes may be insulated with non-asbestos containing material, but have mastic or plastered joints which do contain asbestos. Insulation materials which contain asbestos are generally found in boiler rooms, chiller rooms, in pipe chases in walls, and in pipe runs above suspended ceilings. Insulation which is covered with an undamaged jacket or wrap is classified as non-friable. Adhesives used to hold insulation in place are also non-friable materials. Most other types of thermal insulation are friable. 3. Miscellaneous Materials: Miscellaneous building materials are materials which are used for finishing of interior spaces, or adhesive materials applied to building materials and roofs. These materials have been manufactured with asbestos for strength enhancement, fire-retardation, condensation control, acoustical dampening, or corrosion resistance. The most common type of miscellaneous material is ceiling tile. Most other miscellaneous materials are non-friable materials such as vinyl floor tile, adhesives, and cementitious panels (Transite).

4 Page 3 ASBESTOS SURVEY RESULTS The following table indicates the materials identified in this survey that contain greater than one (1%) percent asbestos. The findings apply to all units. Material Location Asbestos Content Floor Tile & Mastic Floors in each unit Floor Tiles / Mastic = 2% Chrysotile Door & Window Caulk Doors & Windows Caulk = 2% - 3% Chrysotile Black Vent Mastic Roof Vents Vent Mastic = 5% Chrysotile DESCRIPTION: Floor Tile & Mastic SAMPLE NUMBERS: 5B, 6A, 6B, 7A, and 7B. LOCATION: Floors in all units FRIABILITY: Nonfriable CONDITION: Fair POTENTIAL FOR DAMAGE: Low EXPOSURE POTENTIAL: Low DESCRIPTION: Door & Window Caulking Material. SAMPLE NUMBERS: 2A, 2B, 3A, and 3B. LOCATION: Around door openings in each unit. FRIABILITY: Nonfriable CONDITION: Fair POTENTIAL FOR DAMAGE: Low EXPOSURE POTENTIAL: Low DESCRIPTION: Black Vent Mastic SAMPLE NUMBERS: 16A & 16B. LOCATION: Exterior Roof Vents FRIABILITY: Nonfriable CONDITION: Fair POTENTIAL FOR DAMAGE: Low EXPOSURE POTENTIAL: Low ASBESTOS SURVEY CONCLUSIONS

5 Page 4 Survey results indicated the presence of asbestos above the allowable limit of 1% in floor tiles, floor tile mastic, door & window caulking material, and black vent mastic. All asbestos containing materials should be removed. No asbestos was detected in other bulk samples including roofing material, tile & grout, bathroom caulking material, plaster, sheetrock tape & mud, attic insulation, vinyl base molding, light heat shields, and clear vent mastic. Proper removal, storage, and disposal of asbestos containing materials should be conducted by a licensed contractor prior to renovation work according to local, State, and Federal regulations. Laboratory results and chain of custody forms are included at the end of the report. LIMITATIONS This report is intended for the sole use of The Warner Robins Housing Authority. The intent of the report is to aid the building owner, architect, construction manager, general contractors and potential demolition and abatement contractors in locating asbestos. As actual site conditions and quantities should be field verified, this report is not intended to serve as a bidding document or as a project specification document. The scope of services performed in execution of this evaluation may not be appropriate to satisfy the needs of other users, and use or re-use of this document or the findings, conclusions, or recommendations is at the risk of said user. Although every attempt has been made to identify ACM in the areas identified, the inspection technique used is inherently limited in the sense that only full demolition procedures will reveal all building materials of a structure. Additionally, the passage of time may result in a change in the environmental characteristics at this site. This report does not warrant against future operations or conditions which could affect the recommendations made. The results, findings, conclusions and recommendations expressed in this report are based only on conditions that were observed during HC's inspection of the site. We appreciate the opportunity to be of service to The Warner Robins Housing Authority on this project and look forward to working with you on future assignments. In the meantime, if you have questions about information in this report or if we can be of further assistance, please feel free to contact us. Sincerely, Holley Consultants, Inc.
